Description

The invention relates to a transport engineering, in particular to tracked machines, designed to perform various logging operations, and can be used both in the manufacture of these machines and in their operation in logging operations.

The purpose of the invention is to reduce metal consumption and simplify the design. FIG. 1 shows the proposed machine, a general view; in fig. 2 - connection to semi-frames, plan; in fig. 3 view A on fig 2.

Articulated tracked vehicle contains: steering wheel 1, power plant 2, front half frame 3, undercarriage / front half frame, support rollers 5, rear half frame 6, rear axle undercarriage 7, tracked bypass 8 and drive wheel 9. Horizontal hinge 10 consists of a sleeve 11, a torsion 12, an intermediate lever 13. A sleeve 11 connects half-frames 3 and 6, and on one half-frame 3 it is fixed with the help, for example of bolts, and the second half-frame 6 is free, with the possibility of swinging on the sleeve 11 , Inside the sleeve 11 coacia But the torsion bar 12 is located, which is fixed at one end, for example using slots in sleeve 11, and is connected to the other end, for example, by means of slots to an intermediate lever 13, the opposite end of which is fixed, for example, using bolts 15 on the second half-frame 6 in one from threaded holes 1b. Technological equipment 17 is installed on the rear frame 6.

Articulated tracked vehicle operates as follows.

When the machine is moving on the ground with small unevenness of the soil, the front 3 and rear 6 semi-frames do not react to these irregularities and the articulated parts of the machine practically perceive the loads as a single system. This is achieved due to the fact that torus Sion 12 is fixed with a preload in the sleeve and through an intermediate snarl, 13 on the rear half of the frame. from half-frames it is moved relative to the other in a vertical plane, with

In this way, the torsion bar 12 is twisted, partially damping and optimally redistributing the load between the semi-frames (modules). This improves the smoothness of the machine, which favorably affects the operating conditions of the operator and the durability of both the undercarriage system and the machine. When it becomes necessary to increase or decrease the degree of pre-tightening of the torsion and thus change its rigidity, unscrew the bolt 15, securing the intermediate lever 13 to the rear frame 6, then, depending on the required degree of preliminary tightening of the torsion, screw the bolt 15 into one of the threaded holes 16.

In case there is a need to connect any of the other technological modules to the front half frame (energy module), half-frames 3 and 6 are divided and half-frames 3 of the energy complex are combined with half-frame 6 of the technological module with another complete set of technological equipment. To break down the half-frames, loosen the bolts k of the sleeve 11 to half-frame 3, unscrew the bolt 15 of the intermediate lever 13 to the rear half-frame 6, remove the torsion 12 with the intermediate lever 13 from the sleeve 11 Reverse the half-frame of the energy and technology module. In case it is necessary to change the torque of the torsion, then unscrew the fastening bolt 15 of the intermediate lever and through this lever increase or decrease the twist angle of the torsion, then screw the bolt 15 into one of the threaded holes 16.
